Special Issue Information

Dear Colleagues,

In the era of environmental challenges and climate changes, many countries have committed to the “2030 Challenge” targeting that all new buildings and major renovations shall be carbon neutral by 2030. Hence, attention is directed to reduce carbon emission for construction materials. Developing low-carbon binding systems, using efficient energy technologies to reduce the dependence on fossil fuel, and recycling various industrial waste materials to save natural resources are serious attempts for construction materials sustainability development. In fact, the serviceability and durability of construction materials are also essential to achieve sustainability. Long lifespan construction materials will exhibit a low life-cycle carbon impact. Therefore, sustainable and green constructions aim to avoid or reduce depletion of natural resources, prevent environmental degradation, reduce energy consumptions, enhance the quality of life, and create healthy built environments that are safe, resilient, and cost-effective. These green construction practices will lead to carbon-neutral construction materials.

This special issue promotes alternative sustainable construction methods to conventional ones through seeking novel and cutting-edge researches.  Topics of interest include but are not limited to:

  • Material selection and sustainable design
  • Structural sustainability
  • Alternative materials, recycled materials, and material resilience
  • Rheology, strength, and durability of green concrete
  • Structural behavior of green concrete structures
  • 3D-printing techniques
  • Energy-efficient buildings
  • Eco-friendly construction strategies
  • Green building practices
  • Sustainable repair and strengthening techniques
  • Carbon upcycling technologies
  • Sustainable structure performance
  • Life-cycle cost assessment of green buildings
  • Modeling sustainable behavior and case studies

Self-compacting concrete (SCC) became a strong candidate for various construction applications owing to its excellent workability, low labor demand, and enhanced finish-ability, and because it provides a solution to the problem of mechanical vibration and related noise pollution in urban settings. However, the production of Portland cement (PC) as a primary constituent of SCC is energy-intensive, contributing to about 7% of global carbon dioxide (CO2) emissions. Conversely, the use of alternative geopolymer binders (GBs) in concrete can significantly reduce the energy consumption and CO2 emissions. In addition, using GBs in SCC can produce unique sustainable concrete with unparallel engineering properties. In this outlook, this work investigated the development of some eco-efficient self-compacting geopolymer concretes (SCGCs) obtained by incorporating different dosages of fly ash (FA) and ground blast furnace slag (GBFS). The structural, morphological, and mechanical traits of these SCGCs were examined via non-destructive tests like X-ray diffraction (XRD) and scanning electron microscopy (SEM). The workability and mechanical properties of six SCGC mixtures were examined using various measurements, and the obtained results were analyzed and discussed. Furthermore, an optimized hybrid artificial neural network (ANN) coupled with a metaheuristic Bat optimization algorithm was developed to estimate the compressive strength (CS) of these SCGCs. The results demonstrated that it is possible to achieve appropriate workability and mechanical strength through 50% partial replacement of GBFS with FA in the SCGC precursor binder. It is established that the proposed Bat-ANN model can offer an effective intelligent method for estimating the mechanical properties of various SCGC mixtures with superior reliability and accuracy via preventing the need for laborious, costly, and time-consuming laboratory trial batches that are responsible for substantial materials wastage.
